Subject: [PATCH] platform/x86: amd-pmc: Add device HID for AMD PMC
|
|
|
|
The Surface Laptop 4 appears to have used AMD0005 for the PMC instead of
|
|
the AMDI0005 which would match the ACPI ID Registry.
|
|
|
|
AMD appears to have previously used "AMD" in a number of IDs in the past,
|
|
and AMD is not allocated to any other entity as an ID, so adding this ID
|
|
should not cause any harm.

Subject: [PATCH] ACPI: PM: Include alternate AMDI0005 id in special behaviour
|
|
|
|
The Surface Laptop 4 AMD has used the AMD0005 to identify this
|
|
controller instead of using the appropriate ACPI ID AMDI0005. The
|
|
AMD0005 needs the same special casing as AMDI0005.
